Abstract: LARGE DIAMETER BIT WITH BRIDGE MOUNTED DRIVE STEM          Abstract of the Disclosure A drill bit is shown for enlarging a pilot hole into a larger diameter hole by disintegrating the earth formations that surround the pilot hole.  The bit includes a cutterhead with a multiplicity of saddles containing rolling cutters for contacting and disintegrating the formations that surround the pilot hole.  The rolling cutters are mounted so that the cutter face profile of the cutters extends in a uniform manner to the edge of the pilot hole and eliminates uncut bottom.  A drive stem or stinger projects from the cutterhead.  The lower portion of the drive stem or stinger comprises extensions that reach over or "bridge" the inner legs of the center saddles and extend into the available vacant areas between the saddles for attachment to the body of the cutterhead.

Abstract: ABSTRACT OF THE DISCLOSURE     A surgical fastening device for joining soft body tissues comprises an elongated retainer strip of absorbable material having longitudinally spaced openings and arranged to be positioned on one side of the tissues to be joined and an elongated fastener strip of absorbable material having prongs spaced corresponding to the spacing of the openings.  Each prong is insertible through the tissues between the strips and into one of the openings to secure the tissues between the strips.          Barbs on the prongs retain them in the openings.  An elongated rigid anvil member supports the retainer strip during the tissue joining procedure, and a rigid pusher member is engageable with the fastener strip during the tissue joining procedure whereby relative movement between the anvil and pusher members permits the strips to be moved together into fastening engagement with the tissues.

Abstract: Abstract This invention is directed to a process for producing flame retardant flexible polyurethane foams having a porosity in the range of between 0.5 and 10 cubic feet per minute. A polyol have an average molecular weight between about 250 and about 6,500 is reacted with toluene diisocyanate which comprises a mixture of the isomers of 2,4- and 2,6- toluene diisocyanate. The concentration of 2,4- toluene diisocyanate isomer is not critical. The formulation of the present invention includes a flame retardant mixture of plasticizer and dibromoneopentyl glycol. The plasticizer is either a halogenated phospho-nate or halogenated phosphate ester. Chlorine is the preferred halogen atom. The weight ratio of those ingre-dients is between about 50/50 and about 90/10 with the ratio 85/15 preferred. The concentration of that mixture is from about 1 to about 20 percent by weight of the polyol. Other ingredients that can be included in this formulation are water, a silicone surfactant, a tertiary amine catalyst, a tertiary amine co-catalyst, an auxiliary blowing agent and a tine catalyst. This process results in foam products that are flame retardant and suitable for automotive and furniture applications.

Abstract: ABSTRACT OF THE DISCLOSURE         A mixture of finely divided, particulate edible materials, including at least one material which acquires surface stickiness when moistened and a chemical leavening system is contacted with a spray of water and formed into pellets on a pelletizing disc.  The moist pellets are contacted with a stream of hot air to effect reaction of the components of the leavening system with the release of carbon dioxide gas to provide the pellets with a porous cellular structure, and to dry the pellets.  The resulting dried pellets have a crisp, crunchy, friable texture, and sufficient mechanical strength to permit the pellets to be compacted at a pressure of 500-750 psi without crumbling or disintegration of the pellets.  If desired, the pellets may be coated with an edible fat having a relatively high melting point to produce porous, non-hydrating food pellets.  The porous pellets, with or without the fat coating are combined with one or more proteinaceous materials and a binder, and compressed into a compact, cohesive food bar.

Abstract: ABSTRACT           To reduce overvoltages when switching high-voltage circuit breakers, particularly when connecting unloaded overhead lines, closing re-sistors are used which, during closing of the breaker, are connected in parallel relationship with the main switching gap of the circuit breaker by means of an auxiliary switching gap.  After the main switching gap is closed, the closing resistor is disconnected by opening the auxiliary switching gap before the main gap opens and keeping the auxiliary gap open until the main switching gap is reclosed.  For this purpose, the high-voltage circuit breaker includes a movable auxiliary contact pin which is spring loaded in the opening direction of the auxiliary switching gap, and a connecting rod which is linked to the auxiliary contact pin and is connected, hinged, to a rotatably supported crank drive of the drive unit of the breaker.  The crank drive has a curved slot which forcibly guides one end of the connecting rod and comprises a first curved portion which is concentric with a rotating shaft for the crank drive, and an adjoining straight portion which is disposed at the end of the curved portion located along the direction of rotation of the crank drive during closing of the breaker and is disposed approximately radially outwardly with respect to the crank drive shaft.

Abstract: ABSTRACT            A pipe connector for connection to a pipe having a plain end comprises a body having a profile matching that of the pipe, and a pair of jaws extending outwardly for insertion within the end of the pipe.  The jaws are formed with oppositely directed clamping surfaces for engaging the inner wall surface of the pipe end.  One of the jaws is fixed and integral with the body.  The other jaw is pivotally mounted on the fixed jaw and is extended inwardly of the body where it is threadedly engaged by a screw which connects the pivoted jaw with the body so that by rotating the screw in the appropriate direction the pivoted jaw pivots away from or towards the fixed jaw to clamp or unclamp the jaws from the pipe.  The screw thus provides a positive clamping force which greatly assists the dismantling of the connector from a pipe end when desired. The screw also retains the pivoted jaw in place and there are no loose parts to become lost.
